mm ANDERSON, OI CHICAGO, ILLINOIS A FILING CHINE Application fled s m a, mac. and I0. mass.

The resent invention is related to machines or filing metals and otherhard materials, and is more especially concerned with. the machine illustrated, described andclaimed in m pending application for Letters Patent 0 ,the United States filed J uly,5, 1928, Serial No. 290,653. x i

The object of the present invention is to improve certain features of the machine 'referred to,.having particularly in mind'the mountings of the filin elements and the carrier for the same, w .ereb the machine is rendered more efiicient and its durability and life increased.

In addition to the general object stated other objects will appear as the nature of the, improvements is better understood, the invention consisting substantially inthe novel construction, combination and arrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and finally pointed out in the appended claims. In the drawings: v Fig. 1 is a front elevation of a filing machine embodying the present invention, the front ofthe machine casing being removed; -Eig'. 2 is a fragmentary side elevation, on an enlarged scale, and partially in section, illustratin the relation of the upper and lower gui es to the table or work support; Fig. 3 is a sectional plan view, on the line 3-3, Fig. 2; p

rining part; of the file Referring now in detail to the aocompangin-g drawings, the numeral 15 designates t e supporting frame of the machine. It includes a base 16 b which the machine is secured to the sur ace on which it is to be placed, and also a head 17. Journaled-for rotation in the frame-11 is a driving wheel 18, and adjustably mounted on the ead 17 .is an idler wheel 19. Power is applied to the driving wheel 18 from any suitable source. The idler wheel 19 is adjustably mounted on the head 17 for movement towards and away from the driving wheel 18, any suitable mechanism, conventionally illustrated at 20, being employed for efiecting this adjustment of the wheel 19.

Trained over the wheels 18 and 19 is an endless carrier 21 for. the filing elements. This carrier includes a series of elongated file supports 22, and each of said supports is slotted at each of its ends, as at 23, said slots being open at one side, but closed at the side opposite thereto. Pivotally mounted in one of said slots 23, is a male link member 25, the pivotal point of said member being in proximity to the mid portion of the filesu port 22. The outer extremit of the ma e link member projects beyon the contiguous end of the file-support 22, and is erforated in order to receive a intle 26 w ich is also positioned in a forked ead 27 carried by a female link member 28 associated with y the immediately contiguous file support 22.

Thus each two adjacent file supports 22are so connected as to readily flex or break joint 35 with respect to each other in the manner hereinafter described.

The female link members 28 are pivotally mounted in the slots 23 of the file supports 22- at the ends of said supports which are opposite to the slots in which the male link members 25 are pivotally mounted, said fe-- male link members being held inpivotal re 1 lation to the file supports 22 by, the pintles 29; In the mounting of the female link members 28 within their respective slots theforked members 27 thereof project beyond the adjacent end ofthe-file support, and in the swinging movement'of the female link members with respect to'their respective file supports. the forked members 27 thus are free for clearance with respect to these supports. As thus constructed, the file carrier comprises a plurality of the file supports 22 which, in the vertical stretches of the carrier are longitudinally aligned, but which break joint as they pass around the Wheels 18 and 19, thus permitting the carrier to flex with respect to the wheels and prevent its displaceerence to the file supports 22, and likewise maintaining the alignment of the latter in relation to each other. 1

Each of the file supports 22, at points adjacent to the ends thereof, is provlded with oppositely disposed openings'30 and 31. The openings 31 are of larger diameter than the openings 30, as clearly shown in Fig. 8, the purpose of this being to permit the passage of screws 32 through the openings 31 for positioning said screws in the openings 30 through which they pass for engagement with threaded openings 33 in the filing elements 34. The heads of the screws '32 fit snugly within the slots 23, the inner ends of the openings 30 being countersunk for this purpose, so that the heads of said screws are out'of the path of the swinging movement of the links 25 and 28 and the latter are free from interference by the screws.

The file elements 34 may be of any suitable construction, the length of the same being such that the extremities project beyond the ends of the file supports 22 and overlap the projecting ends of the link members 25 and 28. In the vertical stretches of the file carrier the file elements are substantially aligned, their adjacent ends being in suflicient proximity to each other to present substantially .a continuous surface in their passage over the work.

The base 16 has a work table or support 35 suit-ably connected thereto, and adjustable with relation to the base, as illustrated and described in my pending application Serial- No. 290,653 hereinbefore referred to. This work table is perforated so that the file 'carrier and the filing elements mounted thereon may pass through said table. It is essential that the construction of the file carrier be such as to permit its separation at an appropriate point, in order to train the file carrier through the opening of the work table or support 35. To this end the pivotal connection of one of the male link members 25 is in the form of a removable pin 36, the construction of which appears in Fig. 7. One end of the pin 36 is grooved, as at 37, circumferentially of the pin, thereby providing a head 38 at the outer end'of the pin 36. The

and when said pin has been withdrawn the male link member 25 of which it serves as a pintle may be readily separated from the slot 23 of the file support 22 which it occupies, thus disconnecting the male link member 25 from said file support so as to free the file carrier for withdrawal from the opening of the work table or support 35.

In order to permit proper gripping of the remoVable pin 36 to withdraw the same from the file support 22 in which it is seated, the side of said support is provided with an elongated slot 41 that intersects the opening of the support which receives the pin 36. This slot 41 enables the introduction of a suitable tool to the rear of the head 38 of the pin, whereby to effect the desired pull on said pin to remove the same when such is desired.-

The head 17 of the frame has a depending arm 42 which supports an upper guide designated generally by the numeral 43. A lower guide 44 of similar construction is car-- ried by the base 16 of the frame 15, and is positioned beneath the work table or support 35 in vertical alignment with the upper guide 43. These guides are employed so that the file sections will be rigidly supported as they pass through the opening of the work table or support 35 and as the work thereon is pressed against the file elements. The construction of the upper and lower guides 43 and 44 is substantially the same, and this construction is clearly shown in Figs. 2 and 3, in which latter a sectional plan view of the upper'guide is disclosed. The lower end of the. arm 42 supports a guide plate 45 which is bolted or otherwise suitably fastened to said arm 42 as at 46. A vertical series of freely rotatable guide rollers 47 is arranged at the face of the arm 42, each of said rollers being held upon'said arm by a headed stud 48 secured in the arm 42 by a set screw 49, and said rollers 47 are contacted by the file carrier 21 in its passage through the guide 43.

Also carried by the arm 42, and arranged at right angles to the -rollers 47, is a vertical series of rollers 50, the latter also being held to the arm 42 through the medium of a series of headed studs 51 secured in place by set screws 52. The rollers 47 and 50 resist the movement of the file carrier'21 in planes at right angles to each other, thus insuring passage of the file elements to the work in a 1,ee1,74a

rigid manner, and also resisting ressure of naled thereon. The journal of each of said rollers is constituted by a headed stud fitted into the clamping block 53 and-held therein by a setscrew 56. The'flanges' 57 of-the rollers 54 are V -shaped and engage a V-shaped groove 58 formed at one side of each of the file supports 22 as these supports pass through the upper guide. The clampmg block 53 is laterally movable, being guided in such movement by the guide plate 45, assisted by a pair of parallel guide fingers 59 which are received by corresponding recesses 60 formed in the arm 42. The movement of the clamping block 53 is controlled by an adjusting screw 61 having an operating head 62 at its outer end and a shouldered neck 63 adjacent thereto. The shank of the adjusting screw 61 is freely rotatable in the block 53, a clamping collar 64 being carried by said shank, and between said collar and the shouldered neck 63 is fitted the clamping block 53 so that in the movement of the. screw 61 the block 53 will be caused to move therewith towards and away from the arm 42. By proper adjustment of the screw 61 the flanged rolls 54 are caused to approach the file carrier or be moved away om the same, and when properly presented to the file carrier the V-shaped flanges 57 of the rolls 54 will enter the V-shaped groove 58 of the file supports, and thus establish additional guiding means for movement of thefile carrier in relation to the guide.

The lower guide 44 as above indicated, is

of the same construction as the upper guide 43. By reason of being positioned beneath the work table or support 35 the lower guide is somewhat more'inaccessible than the upper guide, and adjustment of the clamping block 53 thereof is somewhat less convenient. To overcome; this the shank of the adjusting screw 61 is elongated so that the operatin head 62 thereof will project beyond the wor table or support 35 to be easily grasped by the operator and manipulated when it is desired to adjust the clamping block 53 of the lower guide in relation to the file carrier.

The wheels 18-and 19,, and all portions of the file carrier save the portion between the" upper and lower guides 43 and 44 and said guides, are enclosed in a casing or housing 65 of sectional construction, the section's'thereof being hinged together. This conceals the moving parts of the machine, with the exception of thepo rtion of the file carrier between the guides 43 and 44 and the guides from possible contact by the operator and injury of the latter in the movement of these parts.

In the operation of the herein described machine, the work to be filed is supported by the work table or support 35. It is moved towards the file carrier and the filing elements 34 mounted thereon. As the filing elements pass the work, the latter being presented for contact with the filing elements, a cutting action ensues until the work has'been reduced to the desired extent.

If it be desired "to file the interior ofithe object under treatment. the-pin 3.6 is removed so as to separate the file carrier at that point. One end. of the carrier is then passed in operation and filing of the interior of the object under treatment efiected.
